Along with financing the wind site, GIG has also established Candela Renewables, which will develop solar projects exclusively for GIG as it moves into North America.

"The [US] platform will focus on asset creation in the renewables sector, principal investment and financing solutions that span all stages of the project lifecycle, including development, construction and operations," GIG said.

Chris Archer, head of green energy in the Americas for Macquarie Capital, added: "We believe that the renewables sector in North America is poised for a prolonged period of growth as falling technology costs combined with growing demand from corporates and utilities drive increasing deployment."

The UK's Green Investment Bank was set up in 2012, with the purpose of investing in remewable and low-carbon projects, in a bid to encourage further private investment in to the sector.
